What two changes on the equilibrium, `N_(2) (g) + 3 H_(2) (g) hArr 2 NH_(3) (g) , Delta H= -92.4" kJ."` can keepitsstate undisturbed ?

Explanation

To determine the changes that can keep the equilibrium of the reaction \( N_2(g) + 3 H_2(g) \rightleftharpoons 2 NH_3(g) \) undisturbed, we need to analyze the effects of temperature and pressure on the equilibrium position based on Le Chatelier's principle.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
The given reaction is:
\[
N_2(g) + 3 H_2(g) \rightleftharpoons 2 NH_3(g)
